Technical Overview
2022 Yuki 125i Matrix III Technical Analysis & Specification Breakdown
Engineered by Yuki for the scooter motorcycle segment, the 2022 Yuki 125i Matrix III utilizes a 125 cc (7.6 cu in) single cylinder, four-stroke layout. In factory specification, peak output is rated at 7.1 HP (5.2 kW) at 7,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 56.8 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the 125i Matrix III measures 118 kg (260 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (16.62 kg per horsepower). Rider ergonomics and chassis geometry center around a 750 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,560 mm (61.4 in) wheelbase engineered for planted straight-line stability. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 80 km/h (50 mph).
